RING AND TRAVELER FOR SPINNING AND TWISTING FRAMES Filed Nov. 19, 1941 Patented Sept. 1, 1942 RING AND TRAVELER FOR SPINNING AND TWISTING FRAMES William Grant Harrison, Decatur, Ala.

Application November 19, 1941, Serial No. 419,792

7 Claims.

formed of threadedly connected sections and provided with an upwardly opening groove for receiving the tail piece or base of a free running traveler; said groove having a restricted upper portion through which a part of the yarn engaging portion of the traveler loosely extends,

and its base portion or tail piece being remov able from said groove only by disconnecting the ring sections.

Still another objectof the invention is to provide a'novel construction of traveler including a yarn engaging portion forming a strand of wire bent into hook shaped form and having trunnions at the shank end thereof, and a' pair of fibre shoes having openings for loosely receiving the trunnions and which are adaptedto slidably engage the annular groove of the spinning ring.

Other objects and advantages of the invention will hereinafter become more fully apparent, from the following description of the drawing, which illustrates a preferred embodiment thereof, and wherein:

Figure 1 is a top plan view of the spinning ring and traveler,

Figure 2 is an enlarged transverse vertical sectional view taken substantially along the plane of the line 2-2 of Figure 1,

Figure 3 is an enlarged transverse vertical sectional view taken substantially along the plane of the line 3-3 of Figure 1,

Figure 4 is a horizontal sectional view of a portion of the ring and traveler taken substantially along a plane as indicated by the line 4-4 of Figure 3, and

Figure 5 is a vertical sectional view of the same taken substantially along a plane as indicated by the line 55 of Figure 3.

Referring more particularly to the drawing, whereinv like reference characters designate like or corresponding parts throughout the different views, In designates generally the improved spinning ring and II designates generally the improved free running traveler.

The spinning ring it includes an inner section I2 which is relatively wide from top to bottom or axially, and which is provided, substantially intermediate of its top and bottom edges. with an outwardly projecting annular flange l3. Flange 13 has a threaded periphery l4. Above the flange l3, the outer side of the ring I2 is provided with an annular recess I5 which terminates below the upper edge of the ring section I2 to form thereabove an outwardly projecting annular flange 16 which extends substantially to the periphery of the outer side of the section i2. The spinning ring l0 also includes an outer ring section I! having an enlarged internally threaded lower portion I8 which engages the threads I. The section I! is provided with an inwardly extending downwardly facing shoulder l9, above the portion I'B, which is adapted to rest flush against the upper side of the outer portion of the flange i3. Section I! has an inwardly facing annular wall 20, above the shoulder l9 which is disposed in opposed relationship to the inner wall 2| of the groove I5, and which is spaced outwardly therefrom to form an annular groove 22. Above the wall 20 and at the top of the section i1, said section is provided with an inwardly extending annular flange 23 which is spaced outwardly from the flange i6 and which is disposed in opposed relationship thereto to form therewith an annular passage 24 which opens at its bottom into the groove 22 and which opens at its top, outwardly of the topof the ring I 0. The flanges l6 and 23 havecorresponding opposed walls 25, defining the sides of the passage 24 and which are provided with outwardly bevelled upper portions 26 which enlarge the upper part of the passage 24.

The traveler ll includes a strand of wire or a rod 21 the upper portion of which is bent into hook shaped form. The strand of wire 21 is provided with a depending shank 28, a Portion of which is loosely disposed in the passage 24 and the lower end of which is provided with an enlarged head 29 which is disposed in the groove 22. The head 29 is provided with trunnions 30 which project from opposite sides thereof and laterally of the roove 22. A pair of elongated fibre shoes 3| are connected to the trunnions 30. The fibre shoes 3| are provided with transverse openings 32, intermediate of their ends, for receiving the trunnions 30, which are tumably mounted therein and for positioning the head 29 between the shoes 3|. As best seen in Figure 4, the shoes 3| are curved longitudinally with the outer side of the inner shoe 3| curved to conform to the curvature of inner wall 2| and the outer side of the outer shoe ll curved to conform to the curvature of the outer wall 2| of the groove 22, which said aforementionedsides are adapted to slidably engage. As best seen in Figure 5, the shoes ii are tapered at their ends by being bevelled on their upper and lower sides as seen at 38. The hook shaped upper portion of the wire or rod 21 extends inwardly of the ring I. and the intermediate part 24 thereof forms the yarn engaging portion of the traveler II. The hook portion of the wire or rod 21 opens in a direction outwardly of the ring I.

The traveler II is adapted to revolve around theringllbythepressureoftheyarnontheyarn engaging portion 34 when the yarn is wound onto the bobbin, in a conventional manner. The shoes 2| run freely in the groove 22 and are retained therein by the flames It and 22. Head 29, trunnions 20 and shoes II comblue to form the base or tail piece of the traveler ll, designated generally ll, which is to be lubricated from time to time by a few drops of oil inserted into the groove 22 through the passage 24. As the groove 22 opens upwardly the oil will be retained therein and some of the oil will be absorbed or will impregnate the fibre shoes 3| so that said shoes will lubricate the surfaces of the groove 22 with which they come in contact. Connection of the trunnions 20 with the shoes II will allow the wire or rod 21 to rocklongitudinally of the shoes and said shoes are disposed sufiiciently loose in the groove 22 to permit a limited lateral rocking movement of the traveler ll.

Various modifications and changes are contemplated and may obviously be resorted to, provided they fall within the spirit and scope of the invention as hereinafter defined by the appended claims, as only a preferred embodiment thereof has been disclosed.

I claim as my invention:

1. A spinning ring having an annular upwardly opening groove, a traveler having a yarn engaging portion disposed above the ring and a base portion slidably disposed in the groove, said base portion including elongated shoes, slidably disposed in the groove, and trunnions connected to the yarn engaging portion and turnably engaging the said shoes to permit the shoes to rock independently of one another relatively to the yarn en a in Portion.

2. A spinning ring having an annular upwardly opening groove, a traveler having a yarn eneasing ion disposed above the ring and a base portion slidably disposed in the groove, and the base portion of the traveler including fibre shoes to each of which the yarn engaging portion is turnably connected, said shoes being curved longitudinally to conform to the curvaturenular fiange at its upper end, concentric with the upper flange of the inner ring section and spaced therefrom. said ring sections combining to form an annular groove of which the first mentioned fiange forms the bed, and said last mentioned fianges combining to form the annular, restricted open upper portion of the groove, said groove adapted to be slidably engaged by a portion of a free running traveler.

4. A spinning ring as in claim 3, said last mentioned flanges being bevelled on their upper sides for enlarging the upper portion of the annular opening formed thereby. v

5. A free running traveler for use with (pinning rings comprising a hook shaped strand of wire forming the yarn engaging portion of the traveler, the shank end of said strand of wire being provided with a head, trunnions projecting outwardly from said head, and shoes turnably connected to said trunnions and adapted to slidably engage the groove of the spinning ring, said head, trunnions and shoes combining to form the base or tail piece of the traveler.

6. A traveler as in claim 5, said shoes being formed of fibre.

' 7. A free running traveler for use with a spinning ring comprising a hook shaped yarn engaging member, and a tail piece including two shoes swivelly connected to portions of the yarn engaging member and movable independently of one another relatively thereto, and adapted to slidably engage a groove of a spinning ring.
